Flourishing-colored yarn fabrication method

ABSTRACT

A flourishing-colored yarn fabrication method includes the steps of: (a) preparing a plurality of tops of different colors; (b) carding the tops of different colors so as to obtain card slivers of different colors; (c) drawing the card slivers into a drawn sliver; (d) roving the drawn sliver into a roving yarn; and (e) spinning the roving yarn into a finished flourishing-colored yarn.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to textile engineering and, morespecifically, to a method of making flourishing-colored yarns.

[0003] 2. Description of the Related Art

[0004] Conventionally, making a piece of cloth to show a color designincludes two methods, i.e., the first method of dying the piece of clothand the second method of using color yarns to weave the desired piece ofcloth. Dying a piece of cloth normally makes the whole piece of cloth toshow a particular color (or color gradation). There are two methods ofweaving colorful cloths with color yarns. One method is to weavecolorful cloths with color yarns each having a single color. The othermethod is to weave colorful cloths with color yarns each havinglongitudinal sections of different colors.

SUMMARY OF THE INVENTION

[0005] It is the main object of the present invention to provide aflourishing-colored yarn fabrication method, which is practical formaking flourishing-colored yarns for weaving cloths having a flourishingcolor design.

[0006] To achieve this object of the present invention, theflourishing-colored yarn fabrication method comprises the steps of: (a)preparing a plurality of, for example, four tops of different colors;(b) using a carding machine to card the tops of different colors so asto obtain card slivers of different colors; (c) feeding the card sliversinto a drawing frame for enabling the card slivers to be drawn into adrawn sliver; (d) using a roving frame to rove the drawn sliver into aroving yarn; and (e) using a spinning frame to spin the roving yarn intoa finished flourishing-colored yarn.

BRIEF DESCRIPTION OF THE DRAWING

[0007]FIG. 1 is a block diagram showing the flourishing-colored yarnfabrication procedure of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0008] Referring to FIG. 1, a flourishing-colored yarn fabricationmethod in accordance with the present invention includes the steps of(a) material preparation, (b) carding, (c) drawing, (d) roving, and (e)spinning.

[0009] During step (a) material preparation, multiple, for example, fourtops 10 a-10 d are prepared from natural fibers such as cotton, linen,ramie, silk, wool, angora, mohair, cashmere, etc., or synthetic fiberssuch as acrylic fibers, polyester fibers, nylon, viscose fibers, etc.The tops 10 a-10 d have different colors. The color range includes red,purple, coffee, black, orange, yellow, green, blue, dark green, gray,and etc. The color of each top can be the original color of the materialof the top itself, or formed by dying. Because the formation of thecolor of each top is not within the scope of the present invention, nofurther detailed description is necessary in this regard.

[0010] During step (b) carding, a carding machine 20 is used to card theprepared tops 10 a-10 d several times (three or four times), so as toremove impurities from the fibers and smoothen the fibers, and tofurther obtain (four) card slivers 30 a-30 d of different colors.

[0011] During the step (c) drawing, the card slivers 30 a-30 d thusobtained are fed into a drawing frame 40, and drawn by the drawing frame40 into a drawn sliver 50 with uniform diameters of fibers.

[0012] During the step (d) roving, a roving frame 60 is used to processthe drawn sliver 50 thus obtained into a roving yarn 70 through a draftaction and a twisting action. According to the present preferredembodiment, a 1/38SMM (spinning metric count) yarn of 40% contractionpercentage (20% or 8% contraction percentage is acceptable) issimultaneously fed into the roving frame 60, and then twisted with thedrawn sliver 50 at 30˜45 T/M (twist per meter), forming a 1/38MM (metriccount) yarn, and then twisted with a 1/38SMM yarn with high contractionpercentage at twist 75 T/M through a left hand twist (S-twist) into theroving yarn 70, which can then be built into a hank, and then steam-setinto a loop yarn at a temperature of 100° C. It is to be understood thatthe loop yarn processing procedure is optional.

[0013] During the step (e) spinning, a spinning frame 80 is used tospine the roving yarn 70 obtained subject to the aforesaid processingsteps into a finished flourishing-colored yarn 90 subject to the desiredcounts (1/1.5˜1/60SMM). The posterior winging, doubling, twistingprocedures are not within the scope of the invention, and therefore nofurther detailed description is necessary.

[0014] The aforesaid yarn fabrication method is absolutely differentfrom conventional woolen, worsted and fancy yarn fabrication methods. Aflourishing-colored yarn 90 made according to the present invention hasflourishing colors. Therefore, using flourishing-colored yarns madeaccording to the present invention can weave pieces of cloths having afine color design. For easy understanding of the product and actualeffect of the present invention, two cloth patch samples are attached.

What the invention claimed is:
 1. A flourishing-colored yarn fabricationmethod comprising the steps of: (a) preparing a plurality of tops ofdifferent colors; (b) carding said tops of different colors so as toobtain card slivers of different colors; (c) drawing said card sliversinto a drawn sliver; (d) roving said drawn sliver into a roving yarn;and (e) spinning said roving yarn into a finished flourishing-coloredyarn.
 2. The flourishing-colored yarn fabrication method as claimed inclaim 1, wherein the number of said tops is
 4. 3. Theflourishing-colored yarn fabrication method as claimed in claim 1,wherein said tops are carded through four carding actions in the step(b).
 4. The flourishing-colored yarn fabrication method as claimed inclaim 1, wherein the step (d) is to feed said drawn sliver obtained fromthe step (c) with a 1/38SMM yarn of high contraction percentage into aroving frame for enabling said drawn sliver to be twisted with said1/38SMM yarn of high contraction percentage at 30˜45T/M (twist permeter) to form a 1/38MM yarn, and then for enabling said 1/38MM yarn tobe twisted with a 1/38SMM yarn at twist 75T/M through a left hand twist(S-twist) into said roving yarn, which is then be built into a hank andthen steam-set into a loop yarn at a temperature of 100° C.
